Frequently Asked Questions

What beam spread (NEMA Type) do I need?

For general area coverage, like a backyard or parking lot, choose a wide flood (NEMA 6x6 or 7x7), which spreads light over 100°+ to cover maximum ground. If you need to illuminate a specific object like a flag, sign, or tree from a distance, choose a narrow spot (NEMA 3x3 or 4x4) to concentrate the light where you need it.

How many lumens do I need for a backyard flood light?

For general backyard illumination, 1,500 to 3,000 lumens is usually sufficient. If you are lighting a large driveway or security zone, look for fixtures with 5,000 lumens or more.

What is a "Knuckle Mount"?

A knuckle mount is an adjustable joint with a 1/2" threaded stem. It screws directly into a standard weatherproof junction box cover or landscape stake. It allows you to aim the light up or down and lock it in place.

Can I use these lights with a dimmer?

Many commercial high output flood lights (typically 50W and above) come with 0-10V dimmable drivers. Smaller residential floods and bullet lights are often non-dimmable unless specified. Always check the product specifications if dimming is required.

What is the equivalent wattage for LED flood lights?

15W LED ≈ 100W Halogen (Bullet Light)

30W LED ≈ 70W Metal Halide

50W LED ≈ 150W Metal Halide

150W LED ≈ 400W Metal Halide (Large Commercial Flood)
